On 5.1-RELEASE and old 5.1-CURRENT, I can use NVIDIA's AGP GART Driver 
until one or two weeks ago of 5.1-CURRENT, I am not able to use it any 
longer. It will lock my machine very hard, which only way I can do is turn 
the power off then boot into single to disable it. Current, I am stuck with 
FreeBSD's AGP GART driver (agp.ko) with Nvidia and it works great, but the 
perferomce descrease.

NVIDIA's AGP GART Driver = The glxgears will go over 3600 fps.
FreeBSD's AGP GART driver = The glxgears will go over 2500 fps.

I really have no idea how I can debug, because it only will lock up the 
machine very hard.

============================
nvidia0_at_pci1:5:0:       class=0x030000 card=0x88911462 chip=0x028110de 
rev=0xa1 hdr=0x00
    vendor   = 'NVIDIA Corporation'
    device   = 'GeForce4 Ti 4200 with AGP 8x [NV28]'
    class    = display
    subclass = VGA
============================

Note: The problem is same on old and new of Nvidia driver, they both behave 
same.
